Summary

Owned by the state and designed by USDA NRCS, this earth dam stands at a height of 29 feet with a hydraulic height of 24 feet. Completed in 1957, it serves the primary purpose of flood risk reduction along TR Barnitz Creek, with a storage capacity of 200 acre-feet and a normal storage of 106 acre-feet.

Managed by the Oklahoma Water Resources Board, this site features a controlled spillway and a single valve outlet gate. Despite being categorized as low hazard potential, the dam's risk assessment is rated very high, highlighting the importance of regular inspections and maintenance. While the last inspection was conducted in 1980 with a frequency of 5 years, the condition assessment remains unrated. With its significant role in mitigating flood risks in the area, SCS-Barnitz Creek Site-067 stands as a vital infrastructure for water resource and climate enthusiasts to monitor and support.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
